Good news for PickyStory users! Whenever you use PickyStory to create bundles and other deals, your inventory is automatically synced with Shopify in real time.
This means that if you create a bundle containing products A, B, and C and your customer purchases this bundle, your inventory levels for products A, B, and C will each be reduced by one in your Shopify backend, automatically.
It also means that if one of the products in your bundle is out of stock, the app automatically recognizes this and your customers are unable to purchase the out of stock product.
